Answer: The first one is A and C
Explanation:
Answer: Particles cannot bend around the edges of an obstacle, as light waves does.
Explanation:
Diffraction happens when a wave (mechanical or electromagnetic wave) meets an obstacle or a slit .When this occurs, the wave bends around the edges of the obstacle or passes through the opening of the slit that acts as an obstacle, forming multiple patterns with the shape of the aperture of the slit.
Note this phenomenon is a characteristic of waves behaviour and not particles, because <u>particles cannot bend around the edges of an obstacle</u>, as waves (light waves in this case) does.
Answer:
c is correct
Explanation:
Steel is a metal that is made from iron and carbon. During the steel making process, iron & carbon are melted together, and is allowed to harden into a solid. The iron and the carbon DO NOT chemically react with each other. After the steel was made, 20 samples were taken from one piece and tested. Each sample contained 98% iron and 2% carbon.
Which of the following terms BEST describes steel? homogeneous mixture

Answer:
creates the necessary male and female gametes
creates gametes with one set of chromosomes
Explanation:
Meiosis is a type of cell division employed by sexually-reproducing organisms. It produces four genetically different daughter cells that have their chromosome number reduced by half i.e. from diploid (2n) to haploid (n). Meiosis is the process whereby organisms produce their necessary gametes needed for sexual reproduction.
Male organism produces haploid male gametes(n) while female organisms produce haploid female gametes (n). These gametes contain one set of chromosome (haploid) because they have to unite in a process called FERTILIZATION. When they do, they form a diloid zygote (2n), which has the same number of chromosomes as each parent cell. That is n+n= 2n.
